• the gripping arm positions the reusable crate (4) at the gripping elements (62), they are activated to exert an aspirating action on the main portion (16) so as to move the cardboard blank (2) in a downwards direction.
• the first pair of rollers (60) and the second pair of rollers (61 ) translate respectively along the first direction (X) and the second direction (Y) in order to abut the first lateral portion (17), the second lateral portion (19), the third lateral portion (19) and the fourth lateral portion (22).
• the second pair of rollers (61 ) accompanies the cardboard blank (2) during the relative movement of the main portion (16) downwards, like the other roller (60b) of the first pair of rollers (60), so that during the advancement of the cardboard blank (2) along the advancement direction (Z), the other roller (60b) of the first pair of rollers (60) can abut the fifth lateral portion (34) with the aim of superiorly covering the group of articles (3a), when received on the main portion (16), in order to realise the box (1 ).
• the machine (100) comprises a pair of pusher elements (51 ) to fold the first flap (35) and the second flap (36) at the same time towards the third lateral portion (19) and the fourth lateral portion (22), while the cardboard blank (2) advances along the advancement direction (Z).
• the adhesive substance is applied on the external wall of the third lateral portion (19) and the fourth lateral portion (22), so that when the pair of pusher elements (51 ) folds the first flap (35) and the second flap (36) respectively towards the third lateral portion (19) and the fourth lateral portion (22), the first flap
• the machine (100) further comprises a further pusher element (53) for folding the contact portion (40) towards the first lateral portion (17) so that they superpose on one another.
• the pusher element (53) is activated first to apply a grip on the box (1 ) so as to maintain the box (1 ) in the closed configuration and, subsequently an adhesive substance is applied at the first lateral portion (17) so that, when the pusher element (53) folds the contact portion (40) towards the first lateral portion (17), the contact portion (40) remains in adherence to the first lateral portion (17) by effect of the adhesive substance, ensuring the closure of the box (1 ).
